Tracking Wintertime Behaviour of Emperor Penguins Using High‐Resolution Synthetic Aperture Radar Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...

A Multi-Stage Enhancement Based on the Attenuation Characteristics of X-Band Marine Radar Images for Oil Spill Extraction

Oceans
Marine oil spills cause significant environmental damage worldwide. Marine radar imagery is used for oil spill detection. However, the rapid attenuation of backscatter intensity with increasing distance limits detectable coverage.

Synergy between synthetic aperture radar and other sensors for the remote sensing of the ocean

, 2001
Over the last decades, satellite remote sensing has proved to be a valuable and effective tool for monitoring physical and biological ocean processes. However there are cases where data from one remote sensor alone cannot be interpreted unambiguously. In

The Application of Autonomous Fixed‐Wing Drones in the Sub‐Antarctic Operating Beyond Visual Line of Sight to Enable Large Area, Multi‐Species Population Monitoring in a Changing Environment

Remote Sensing in Ecology and Conservation, EarlyView.
Autonomous fixed‐wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi‐species baseline reference survey at the sub‐Antarctic island of South Georgia. Long‐term population monitoring in this remote, challenging environment has historically proved difficult, with terrestrial monitoring generally ...

The Hidden Harvest: Harnessing Colorado's Geodiversity and Environmental Heterogeneity for Sustainable Agritourism

Sustainable Development, EarlyView.
ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...

Improving data-driven estimation of significant wave height through preliminary training on synthetic X-band radar sea clutter imagery

Frontiers in Marine Science
X-band marine radar captures the signal reflected from the sea surface. Theoretical studies indicate that the initial unfiltered signal contains meaningful information about wind wave parameters.

Oral Microalgae‐Laden Hydrogels Modulating the Intestinal Microbiota Metabolism for Acute Alcohol‐Induced Liver Injury Therapy

Small, EarlyView.
A food‐grade microalgae‐laden hydrogel (FMH) enables efficient in situ microalgae cultivation and serves as an oral therapeutic platform for acute alcohol‐induced liver injury. FMH improves alcohol tolerance, alleviates oxidative stress, inflammation, and lipid metabolic disorders, restores gut microbial homeostasis, and provides synergistic ...
